Two zero-sum invariants on finite abelian groups
Let G be an additive finite abelian group with exponent exp(G). Let s(G) (resp. η(G)) be the smallest integer t such that every sequence of t elements (repetition allowed) from G contains a zero-sum subsequence T of length |T | = exp(G) (resp. |T | ∈ [1, exp(G)]). Let H be an arbitrary finite abelian group with exp(H) = m. In this paper, we show that s(Cmn ⊕ H) = η(Cmn ⊕ H) + mn − 1 holds for a...
متن کاملOn Zero-sum Subsequences in Finite Abelian Groups
Let G be a finite abelian group and k ∈ N with k exp(G). Then Ek(G) denotes the smallest integer l ∈ N such that every sequence S ∈ F(G) with |S| ≥ l has a zero-sum subsequence T with k |T |. In this paper we prove that if G = Cn1 ⊕ · · · ⊕ Cnr is a p-group, k ∈ N with k exp(G) and gcd(p, k) = 1, then Ek(G) = ⌊ k k − 1 r ∑
متن کاملOn Zero-sum Partitions of Abelian Groups
In this paper, confirming a conjecture of Kaplan et al., we prove that every abelian group G, which is of odd order or contains exactly three involutions, has the zerosum-partition property. As a corollary, every tree with |G| vertices and at most one vertex of degree 2 is G-anti-magic.
متن کاملInverse zero-sum problems in finite Abelian p-groups
— In this paper, we study the minimal number of elements of maximal order within a zero-sumfree sequence in a finite Abelian p-group. For this purpose, in the general context of finite Abelian groups, we introduce a new number, for which lower and upper bounds are proved in the case of finite Abelian p-groups. Among other consequences, the method that we use here enables us to show that, if we ...
متن کاملA Survey of Zero-sum Problems on Abelian Groups
Let G be a finite abelian group. A zero-sum problem on G asks for the smallest positive integer k such that for any sequence a1, . . . , ak of elements of G there exists a subsequence of required length the sum of whose terms vanishes. In this talk we will give a survey of problems and results in this field. In particular, we will talk about Olson’s theorem on the Davenport constanst of an abel...
